There are over a dozen speakers sprinkled throughout my house. Soundbars with powerful subwoofers add thunder to the output of my television and projector, and several high-wattage speakers pump out the music supplied via a set of Alexa Echoes. I even have a 40W Bluetooth speaker that is constantly paired with my tablet, phone, or portable projector. While you might feel my collection is more than large enough, I am on the hunt for one final speaker

When I go for my morning walk, I like to listen to music. While Bluetooth earbuds provide excellent sound, their insulative qualities filter away outside noise. That can be dangerous when jogging during rush hour traffic. I also worry that the earpieces will slip from my ear and fall into the street.

Today I am taking a close look at a Bluetooth speaker that, among its other uses, can be fastened to the same belt that holds my elderly jeans in place. A speaker of this type allows me to keep track of the traffic while sharing my eccentric taste in music with everyone in the vicinity.


The Micro 2 is dark gray with silver and white accents. It weighs 11 ounces. This speaker is mainly composed of plastic with an upper covering of cloth.

Volume control and a multifunction button are positioned at the top of this device. The power button, pairing button, microphone, and battery level indicator are located at the front.

The Micro 2’s type-C port is situated on the left side. This allows the device to be charged or used as a power bank. A handy rubber strap is located at the bottom.

Housed within this unit are a 10W amplifier, 1.75-inch speaker, and a 4700mAh battery. Accessories include a user guide and a type-C to type-C cable.

While hanging a Micro 2 speaker from my scooter's mirror is a bad idea, it could easily be strapped to the handlebar of a bike or motorcycle

Portability and Convenience

Excellent water resistance, light weight, and long battery life ensure the StormBox Micro 2 can be carried and used almost anywhere. I especially appreciate the device’s strong and flexible rubber strap. I securely attached the speaker to various objects, such as my stove’s door handle and a towel rack in the bathroom.

Tablet, Computer, and Smartphone Test

I connected the speaker to my smartphone and opened the Amazon music application. The sound was reproduced faithfully at all volume levels, but some distortion was introduced when set above the 90% mark.

My next test was to connect the StormBox Micro 2 to my tablet. Like the phone, the tablet paired quickly and connected to the speaker.

I accessed my Netflix account and watched a movie. The sound output proved to be excellent.

In further tests, I paired the Micro 2 to both my laptop and desktop. The new speaker easily outperformed the laptop’s built-in speakers and worked well with my main computer.

Projector Test

I tested the Micro 2 in conjunction with the projector mounted to my dining room ceiling. The speaker connected quickly via Bluetooth. I placed it across the room, just below the projector’s screen, and set its volume to 80%.

While the projector’s built-in 5-watt speaker boasts good volume, it is nowhere near as crisp and clear as the sound produced by the StormBox Micro 2.

I, of course, do not plan to use this speaker with my projector. Although reasonably loud and able to emit decent bass, it cannot compete with my powerful subwoofer-equipped soundbar.

After three hours of use, the LEDs measuring the speaker’s battery level had dropped from five bars to four.

Overall Impression

While this tiny speaker's volume will not blow you away, it is quite loud and it punches slightly above its weight when reproducing frequencies in the bass range. The output of the Micro 2 is crisp, clear, and enjoyable.

A large battery ensures up to 12 hours of playing time, and thanks in part to its flexible strap, this speaker can be used in a wide variety of locations and situations.

If you are searching for a reasonably priced Bluetooth speaker with great sound and excellent battery life, take a close look at the Tribit StormBox Micro 2.
